The horse is dead

Then they shouldn’t attempt something like a rocker ratio change.

Go back a few posts and read what the OP said.

I’ll help you. He said the Hughes rockets don’t fit.

But they do fit. He just didn’t know how to make them fit.

Are the Mancini rockers better because they bolt on? Who knows.

But he should go read the tech pages on .B3racingengines.com

Not clueless. It’s called experience.

Before calling me out you need to go read those tech pages several times and then come back and tell me I’m clueless.

But, the only way to gain experience is to keep advancing one step at a time...

You learn as you go along, and this was another attempt for the OP to advance his skills, but Dave didn't want to help him and tell him how to get the parts he sold him to fit...

If you don't take a chance to advance and buy parts for that next step, you won't get to the next level... Learn as you go and don't be afraid to try new things...
